Answer:
C(C^3 + 8C^2 -3C -7)
Step-by-step explanation:
(-3C^4-5C^2-7C)+(4C^4+8C^3+2C^2)
(-3C^4 +4C^4)+8C^3 + ( -5C^2 +2C^2) -7C [Combine like terms]
C^4 + 8C^3 -3C^2 -7C [Simplify]
C(C^3 + 8C^2 -3C -7) [Isolate 1C from the rest]
X= 2 sq rt 3
Y= 3. Sqrt 3 times sqrt 3 =3
Answer:
Step-by-step explanation:
Direct variation can be modeled by y = kx where k is the constant of variation!
So to solve for k all we need to do is substitute in the value for y and x that are given.
So according to the problem y = 24 when x = 6
24 = 6k
Divide both sides by 6
k = 4
So the constant of variation is 4
The direct variation equation would then be
y = 4x
Answer:
2
Step-by-step explanation:
xy/z where x = 3 y = -4 and z = -6
Step 1. Substitute x for 3 y for -4 and z for -6
(3)(-4)/(-6)
Step 2. Multiply
-12/-6
Step 3. Remove the negative signs (only when the numerator and the denominator are both negative numbers)
12/6
Step 4. Simplify
2
